Fix: ChkDsk or Check Disk runs at every startup in Windows 7

The Check Disk Utility in Windows 7 and Windows Vista or Chkdsk.exe is used to check for errors in the disk media and in the file system. If you face problems ranging from blue screens to inability to open, save files or folders, you should run chkdsk.exe. Check Disk can run automatically, in the case of an abrupt shutdown or if it finds the file system to be ‘dirty’. There may be times, when you may find that this Check Disk Utility runs every times your Windows starts. You may have scheduled its run, or your Windows may have decided to schedule its run. But instead of running just once, it continues to run every time your Windows computer boots.

Check Disk runs at every startup in Windows 7

If your Check Disk or chkdsk tool in Windows runs on every boot, here are a few things you may want to try.

1. First of all, let it run once completely.

2. Now open the Registry Editor and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

In the right pane, you will see BootExecute. Change its value from autocheck autochk * /. to autocheck autochk *

bootexecute value 2 Fix: ChkDsk or Check Disk runs at every startup in Windows 7

If this works for you great, else try this :

3. Open a command prompt windows, type the following and hit Enter:

fsutil dirty query g:

This command will query the drive, and more than likely it will tell you that it is dirty.

Next, type CHKNTFS /X G:. The X tells Windows to NOT check that particular drive (G) on the next reboot. At this time, manually reboot your computer, it should not run Chkdsk now, but take you directly to Windows.

Once Windows has fully loaded, bring up another command prompt and type and Chkdsk /f /r g:. This should take you through five stages of the scan and will un-set that dirty bit. Finally, type fsutil dirty query g: and hit Enter. Windows will confirm that the dirty bit is not set on that drive.

You can run the chkdsk /r command or the chkdsk /f command to check a hard disk for errors. But if The chkdsk /r command and the chkdsk /f command take a long time to run on a Windows computer see KB943974.

Hope this helps!

Go here if Check Disk will not run at startup in Windows 7.

    You saved so much of my time by putting up this article. Successfully set the drive to ‘Not Dirty’. :)

    Thanks! You saved my day. I think this occurred due to my incorrect partition management, but yeah, it helped me. Also tried defragmenting, my partition was heavily fragmented, now it’s very clean and healthy.

    Am I to actually use the drive designation G: … or is that illustrative only?

  • Scott

    Never mind. Silly question
